Human intestinal helminths are described in this paper. They can be over a meter long, with an irregular cylindrical shape, resembling a rope. These anaerobic intestinal "rope" parasites differ significantly from other well-known intestinal parasites. Rope parasites can leave human body with enemas, and are often mistaken for intestinal lining, feces, or decayed remains of other parasites. Rope parasites can attach to intestinal walls with suction bubbles, which later develop into suction heads. Walls of the rope parasites consist of scale-like cells forming multiple branched channels along the parasite's length. Rope parasites can move by jet propulsion, passing gas bubbles through these channels. Currently known antihelminthic methods include special enemas. Most humans are likely hosting these helminths.
